469-8586 Caterpillar OEM Drive Coupler

The 469-8586 Caterpillar OEM Drive Coupler is a Caterpillar-numbered coupling used in select Caterpillar diesel-powered industrial equipment. This elastomeric coupling connects the engine output to the driven component – providing torsional damping and vibration isolation in the drivetrain.

Caterpillar equipment operates in some of the most demanding environments in construction, mining, and industrial service. The drive coupler in these machines absorbs the torsional pulses generated by Cat diesel engines, protecting downstream components from vibration-induced fatigue. When the coupling element wears, increased drivetrain vibration can accelerate bearing wear, damage seals, and affect the performance of the driven equipment.

Part number 469-8586 is a direct replacement for the factory-installed coupling. Match this part number against your Cat equipment’s service manual to confirm compatibility. During installation, follow Caterpillar’s specified alignment procedure and torque values. Inspect both hubs and all associated mounting hardware before reassembly.
